Security issues at any Hillcrest campus or site are addressed by the supervisors, administrators and Environment of Care Committee at that campus, as well as by the agency Administrator of Health, Safety & Wellness Programs and Management Team. The agency has established relationships with local law enforcement agencies, and program administrators work in conjunction with local law enforcement agencies as needed. Safety and security in the environment of care, however, are shared benefits and fundamentally necessary conditions for which all employees are responsible. All Hillcrest employees are expected to be aware of and to attend to matters pertaining to safety and security in the course of their work. Employees are expected to report all potential or actual breaches of security or safety as soon as possible.

Program sites also address their unique security issues in ways best suited to their needs, campus setting and goals. For example, Hillcrest Center locks the Tetro Center at night and utilizes a call box at the entrance by which visitors can reach Supervisors on grounds.
